The organization maintains various information in cloud which is a loosely coupled environment. However, the nature of cloud encourages the threats in different level. Among them the data security has been a keen issue being identified and challenges the service provider. To improve the data security performance, different algorithms have been discussed, but suffer to achieve higher performance in data security. To design more secured data security algorithm, a light weight proactive padding based crypto security system (LPP-CS) is presented in this paper. The method generates keys to support the crypto systems based on the prime values. The keys are generated from the set of prime numbers which have been used to pad the cipher text generated. The end user will be given with the key which is generated and distributed at the assignment. The encryption is performed in block level and for each block of data different keys has been used which challenges the adversary highly. The selection of prime factors and keys are suitable for any specific time window and has been iterated frequently. The proposed LPP-CS algorithm improves the performance of cloud data security with less time complexity.

Several factors add to carrying emotions of a person. Posture, speech, facial expressions conduct and exercises are just some of them. Facial appearances are noteworthy in encouraging human correspondence and Associations. Facial appearances can be reflected not just as the most regular Procedure of displaying human feelings yet additionally as a significant to Non-verbal correspondence. Additionally, they are utilized as a noteworthy Device in social investigations and in medicine. In speaking with others, People can recognize feelings of included human with an impressive level of Precision. The issue of programming acknowledgment of outward appearances is yet an ebb and flow inquire about. This framework proposes a programmed outward Appearance appreciation framework, equipped for special the seven all-inclusive Feelings: disgust, anger, fear, satisfaction, trouble and amazement utilizing Profound convolution neural systems. It is intended to be a person independent. As there is a more prominent utilization of human-machine connections nowadays, it is likewise primary for machines to translate the facial ex-pressions and we Would have the capacity to accomplish exactness that is relatively practically Identical to the human mindfulness.
